A Canadian man was allegedly part of a gang that ran a sophisticated ATM skimming scam that was used to steal money from unsuspecting bank customers around Boston.

Such scams typically involve the installation of electronic devices on ATMs to capture information from the magnetic strips of credit or debit cards. Hidden cameras record personal identification numbers associated with the cards.

Norfolk County District Attorney William Keating on Thursday alleged 28-year-old Izaylo Hristov of Ontario, Canada, was part of a gang that loaded the stolen information on new cards to withdraw thousands of dollars from various bank accounts.

Other suspects have not been arrested.

He has pleaded not guilty to the charges. A Quincy District Court judge has ordered the suspect held on $1 million cash bail, or $10 million surety. (AP)
